NOTE: When winterizing, you will definitely want to bypass the Alde system.

Step 1: Drain all the tanks. NOTE: the freshwater tank drain valve is located underneath the entry door steps.

Step 2: Open the hot and cold water drain valves located underneath the seating area by the Alde System – open one at a time to create a pressure system.

Step 3: Lift the Alde Relief Valve (the yellow valve that flips up and down and is connected to the blue water pipe) and allow the Alde hot water tank to drain. (See image below)

Step 4: Once the unit is completely drained, switch all the valves from Camping Season Mode to Winterization Mode. (See image below.)

Step 5: Once you have all the valves in Winterization Mode/ Bypass Mode, add RV Grade antifreeze. Pour 4 to 5 gallons of antifreeze into the freshwater tank, then turn on the water pump to pump it through the system. If you want to save antifreeze, connect a line directly from the pex side of the water pump and pump antifreeze directly into the lines instead of dumping antifreeze into the freshwater tank.

Step 6: Open every faucet one by one (including the shower faucets) until antifreeze comes out to ensure they are protected from freezing.

Step 7: Pump the toilet to make sure the toilet is protected.

Step 8: Pour antifreeze down the traps/drains. Note: The traps are very susceptible to freezing so this step is very important.
